SACK FILLER AND WEISHER.

SPECIFECATIN ;Forming part of Letters Patent No. 321,468. dated July 7, 1885.

(No model.)

T0 all whom ib may concern;

Be it known that l, HENRY. T. WILEY, of Boston, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Im provementin Bag Filling and Veighing Devices; and I dohereby declare the following to be a full, clear, and exact description thereof.

To enable others skilled in the art to make and use my improvement, I will now describe my invention by reference to the accompanying` drawings, in which Figure l is a front elevation. Fig. 2 is a side elevation. Fig. 3 is a Vertical section of the hopper and upper end of the standard. Fig. 4 is a plan View partly in section. Figs. 5 and 6 are views of the hopper. Fig. 7 is a modification.

Like letters of reference indicate like parts.

Mounted on the platform a of a suitable pair of scales is a board. platform, or plate, Z), which is provided with bent cleats or fianges b', engaging the edges of the platform a, to secure it in place, and so that it may slide side- Wise into position. Rising from the plate Z) is a pair of standards, c, grooved vertically on their inner sides, as at c'. Placed in the grooves c' is a Vertically-moving slide,d,which may be secured at any desiredheight by hinged stops d'. This stop may be formed in the shape of a two-leafed hinge, the stationary leaf of which is secured to the standard c, while the other leaf is capable of swinging into and out of the path of the slide. Hinged to the slide d, at or near its upper end, is ahopper, e, having a series of spurs or sharp project-ions, e', at the lower end of the rear side. The lower' half, ez, of the front side is hinged and provided with side wings, 83, in which are segmental slots et, through which guide-pins 85, attached to the side of the hopper, pass. The purpose of this construction is as -follows: Vhen it is designed to put a bag in place for filling, the hopper e is swung forward on its hinge, as shown in Fig. 3, and the open month of the bag drawn up over its lower end until it passes the pins e'. The hopper is then permitted to come back to its normal position, which will cause the rear side of the bag to be impaled on the pins e', while the front side stands around the lower end of the hopper, the hinged part e'z being closed for the purpose of effecting an easy entrunccinto the month ofthe bag. W'hen the material is placed in the hopper,its weight, coming on the hinged portion 02, causes it to move outward and spread the month of the bag, so as to afford alarge charging-hole. The slide d is provided with holes d for the reception of the holding-pins 8'. On the-rear side of the slide is a spring, f, which is connected by a suitable cord, f', to the rear side of the hopper. said cord f' passing through opening]E2 inthe slide. Thepnrpose of this spring is to draw the hopper eback to its normal position after the lower end has been inserted into the month of the bag, as illustrated by broken lines in Fig. 8. 'l`he spring fmay be utilized as a pawl to sustain the slide at any desired height. For this purpose I form the ratchet-rack g on the frame c, and provide the springfwith a suitable edge or lip, fi, capable of engaging with the teeth of the ratchetrack. Then by merely drawing the slide up to the desired place, the spriug-pawl fi, will engage the adj aeent tooth on the ratchet-rack g, and retain the slide in the desired position. This device is preferable to the hinged stops (Z',where a single package or bag is to be filled; but where there are a number of bags to be filled with the same qnantity the proper stop d' is turned into position, and used so as to avoid the trouble of determi' nng the position of the slide by means of the spring-pawlf,which is disengaged every time the hopper is raised to take off a bag. I desire, however, to employ either or bot-h of these devices, according to the purpose to which the hopper is applied.

Thns constructed my improvement is used as follows: The weight of the frame b c, slide d, and hopper e being determined, the scales are adj usted so as to balance therewith. The slide is then raised by taking hold of the hopper, as indicated in Fig. 3, and thelower end of the hopper is inserted the proper distance in the month of the bag, which rests on the plate Z). The hopper is then permitted to be retracted by the spring f, which causes the rear side of the bag to be impaled by the pins c'. The scales being in convenient proximity to the bin or other receptacle which contains the supply of material which is to be placed in the bag, the proper qnantity of the material is transferred from said bin or receptacle into the hopper. The weight opens the hinged side IOO 02, distending the .month of the bag, and delivering the material 'properly thereinto. As soon as the proper quantity is placed in the bag the scales register the fact, so that the filling and weighing` is aeeomplished with precision at one and the same operation, and no lifting of a partially-filled bag onto or oli" the scales is necessary. Then the proper quantity is diseharged in the bag, the hopper c is raised, withdrawing` the pins c' from the rear side of the bag, while the collapsing or closing` of the hinged side et' enables the hopper to be easily withdrawn from the month of the bag. The slide is raised sufiieiently to permit the bag to be tied while still on the scales, so that it is not removed until in complete shape for delivery.

My improvement can be applied to scales of various forms,and its great advantage consists insimplifying and facilitating the Operations offilling and weighing,and in preventing waste and loss of time, which occurs in the present practice of iilling a bag, and then placi ng it on the scales, and then bringing it to the exact weight by subsequent additions or removals. It also prevents unnccessary handling of the package.

In Fig. 7 I show my improvement applied to a counter-scale. Hcrethescale rests on the counter h and the filling applianceis below the counter, being suspended from the platforma. The standards c are extended upward, and at their upper ends are provided with the hools or cleats b', which extend over the edges of the platform a. The construction of 'the other parts remains the same as in the first construction. This arrangement doesnotinterfere with the ordinary use of the scale, and enables my ilnprovementto be utilized for holding and filling small bags at the time of weighing, an important application of the device, and thereby prevents much of the loss and waste of incrchandise which. results from the present manner of filling small bags in retail stores. The holding and filling devices, being` below the counter,are out of the si ght of the public, which conduces to neatness in a store. If the holding and filling appliance is to be used separate from a seale, it can be placed in or in convenient proximity to the bin or bins containing the material with which it is used. I desire to use it both with and without the scale. The uprights c constitute a Vertical frame, having a suitable cross piece or picces, c'-`,when necessary. The plate or board 7) maybe dispensed with in the lirst construction by securing the frame c directly to the platform a.

lVhile I prefer the construction of hopper e shown and described, I do not limit myself thereto, but desire also to use a plain hopper secured to the vertical slide.

\Vhat claim as my in'vention, and desire to secure by Letters Patent, is-

1. Thecombinationofa weighing-seale with a vertically-adjustable bag-holder, consisting of the frame (f, slide (Z, and a hopper sceured to said slide, substantially as and for the purpose specitied.

2. The combination of the platform a with the flanged plate Z), Vertical frame (z, and hopper c, substantially as and for the purposes deseribed.

3. The-combination of the platform (t with the Vertical frame c, slide 1/, and a hopper securcd to such slide, substantially as and for the purposes deseribed.

i. The combination of the frame c, slide (Z, and a hopper seoured to such slide, substantially as and for the purposes deseribed.

5. The combination of the Vertical frame f', slide (Z, and pivoted hopper provided with bagimpaling pins, substantially as and for the pu rposes deseribed.

6. The combination of the fralne c, slide d, hopper c, pawl f, and ratchet substantially as and for the purposes deseribed.

7. The hopper c, provided with impalingpins c' and hinged side 02, substantially as and for the purposes deseribed.

In testimony whereof I havehereu nto set my hand this 5th day of March, A. D. 1885.
